I've a whole new design for it and I was planning on implementing it for v2.2. Do you want to help coding it? :) Which storage would you want to use?
The generic idea is:
- only one server accesses one user simultaneously
- index files are copied from object storage to local filesystem and accessed there, once in a while uploaded back to object storage
- if user is accessed from two servers because of some bug/split brain/something, the changes are merged using dsync
- support high latency: asynchronous reads/writes. prefetch mail bodies. With this system, would the read/write ultimately go to a normal OS file function? If it is a file function, could this be used with a system like glusterfs, ceph, etc? The other option would be to write it against a object store client library and bypass the normal file functions.

Also other users are talking about Ceph and Dovecot
